APPARATUS FOR SPINNING FIBROUS MATERIALS.

SPECIFICATION forming part of Letters Patent No. 511,878, dated January2, 1894.

Application filed March 16, 1893. Serial No. 466,335. (No model.)Patented in Belgium April 15, 1892, No. 99.060. and in France April 19,1892, No. 221,010.

To aZZ whom it may concern.-

Be it known that I, NICOLAS OUPERs, a subject of the King of Belgium,residing at lVeert, in the Province of Limbourg, Netherlands, haveinvented a certain new and useful Apparatus for Spinning FibrousMaterials, (for which I have obtained Letters Patent in Belgium, No.99,060, dated April 15,1892, and in France, No. 221,0lO,dated April 19,1892,) of which the following is a specification.

This invention relates to apparatus for the spinning of fibrousmaterials and by its aid materials having but a short fiber, such aspeat, cow-hair, cotton waste and the like or a mixture of these or likesubstances may be spun directly from a mass into threads or cords of apredetermined size.

The invention may be carried out with an ordinary carding machine inconjunction with the additions and improvements, the nature of which ishereinafter set forth.

The material instead of being submitted as in ordinary spinning to theusual apparatuses which divide it longitudinally in several parts ofwhich each one is twisted individually, is taken from the dofiingcylinder by a comb having a reciprocating motion toward and from thecylinder, the material so taken being gradually formed into a roll bythe aid of a roller located close to the comb and revolving in the samedirection as the doffing cylinder before referred to. The material soaccumulated is drawn out by the action of side rollers practically inthe plane of its length through one or more revolving, twisting, orspinning wheels which may be formed with a hollow shaft and a bellmouthed opening thereto.

To clearly explain the invention reference is made to the accompanyingdrawings, in which- Figures 1, 2 and 8 are respectively a sec tion, anelevation and a plan of the collecting, twisting and drawing portions ofthe apparatus the views being partially diagrammatic. Fig. 4 is anelevation of an ordinary form of wool carding engine having myimprovements applied thereto for the purpose of carrying out thespinning of the above described materials. Fig. 5 is an end view ofsame. Fig. 6 is a plan, and Fig. 7 is a section of the twisting pulley.

Referring to Figs. 1, 2 and 81is the doffing cylinder and 2 the doflingcomb which serves to remove the material 3 from the doffer. The sheet ofmaterial detached by the comb 2 is prevented from advancing beyond acertain point by means of the roller 4 which rotates in the samedirection as the doffer and which causes the sheet of material toaccumulate in the form of the roll 5 from each end of which the materialis drawn out by two pairs of rollers 6.6 after having been previouslysubmitted to torsion by passing through the centers of pulleys 7.7. Fromthe rollers 6 the drawn and twisted thread or sliver may be wound uponspindles of any suitable kind. The twisting pulleys 7. 7 are in the sameplane as the mass 5 which has accumulated between the doffer 1 androller 4. The sheet of material is thus transformed directly into athread from the time of its production or formation into the roll 5. Itwill be evident that by causing the speed of rotation of the drawingrollers 6. 6 to vary, threads of different thicknesses can be readilyproduced.

As shown in the figures referred to the roll 5 is being drawn out fromboth ends but by drawing it out from one end onlya considerably thickerthread can be produced.

In Figs. 4 to 7 the main cylinder 8 is mounted on the shaft 9 carried bythe framework 10 and is driven by the fast pulley 11. The feeding apron13 is adapted to deliver the material to the feed rolls 14, 14 fromwhich it is taken by the stripping and working rolls to the doffer 1,the sheet of material being detached from the latter by the comb 2 whichis attached to the shaft 15 mounted in the bearings 16.16 and receivingan oscillating movement by means of an arm 17 which is attached. by aconnecting rod 18 to a disk 19 keyed upon a shaft 20. The shaft 20receives movement from the driving shaft 9 by means of a belt whichpasses around the pulleys 21, 22 the former being on the shaft 20 andthe latter on the main shaft.

The doffer 1 whose shaft 23 is mounted in the bearings 24., 24 receivesits movement in IOC) the ordinary way by means of the gear wheels 25, 26driven by the pulleys 27. 27 and belt 28.

The roller 4 which collects the sheet 8 and causes it to-accumulate inthe form of a roll 5 is mounted on a shaft 29 supported by bearings 30.30 said shaft being provided at one end with a gear wheel 31 whichengages with a corresponding wheel 32 secured on a shaft- 33 mounted inbearings 34 of which only one is shown. The shaft 33 is fitted withagrooved pulley 35, driven by a rope 36 from a pulley 37 on the mainshaft 9.

The twisting pulley 7 shown detached in Fig. 7 has a flaring mouth andreceives its motion from a rope 38 driven by a pulley 89 from the shaft20. The pulley 7 is mounted in some suitable support which is not shown,from which it may be readily removed, so that pulleys having centralholes of varying sizes may be substituted for the purpose of producingdifferent sizes of threadsthe torsion being proportionate always to thespeed of rotation of the pulley. The rollers 6 6 (of which one set onlyis shown in the machine being described) serve to draw out the 'spread40 after it has passed through the pulley 7, and are of any ordinaryconstruction. They are coupled together by gear wheels and are suitablymounted and preferably operated from the shaft 33 by means of bevelwheels or like gearing.

One or more twisting or spinning wheels and pairs of drawing rollers maybe placed at either end of the cylinder, but as a rule one set at eachend will generally be sufficient. By varying the size of the openingthrough the twisting wheels and the speed of rotation of the variousparts the size of the cord or twisted fiber produced can be varied.After having passed the drawing rollers the thread 40 is wound upon ahorizontal spindle or roller 42 the rotary movement of which is obtainedby its friction against a wooden roller 41 driven by any suitable means,or the winding may be eifected by any other suitable apparatus.

In the spinning of peat, the fibrous parts are first separated from thematerial and are then treated by washing, drying, beetling and hacklingbefore being passed to the carding machine.

In the case of cotton waste, the material is treated in a dry state, 2".e., without a preliminary treatment with oil or a greasy body which anddrawing the material, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.-
